Hi Bill. My reel bundle pics are not the best - sorry. The bug is on the 20 tooth gear for the first reel and is right on top - see the bolt holding the roll over that will not allow the reel stop to stop on that symbol. You can play your machine and stop the clock after the first two clicks (first and second reels stopped). Then manually move the first reel symbol by symbol to see if any roll overs (bugs). Or just play the machine until you see the horse symbol stop eventually on all three reels. 20 to 1 chance on each reel so won't take too long!
